High-yield cultivation method of shrimp in soil pond

Rossian shrimp is also called white-legged shrimp and golden shrimp. It has always been called the king of freshwater shrimps. At present, there are a lot of artificially cultivated shrimps, so it is also a very common edible shrimp. He also has rich breeding experience. But I have never farmed it before. Friends who want to farm it may need to refer to the specific methods of raising Roman shrimp that I will talk about next, including various aspects.

1. Select a species

The origins of Roman shrimp are Thailand and Myanmar. The shrimps produced in the two places are different. The head and chest of Myanmar are smaller, and the foot segments are longer, but the female They are larger than those produced in Thailand, lay more eggs, and are more mobile and predatory. Therefore, you can choose brood shrimp produced in Myanmar for production and breeding.

2. Breeding ponds

Construct a breeding pond in a place with sufficient water resources. The construction area should be within 5 acres, which is easy to manage and can be decided according to your own ability. When building a rectangular pond, the walls and bottom of the pond should be impermeable. Generally, new ponds need to be disinfected with lime. Disinfection is mainly for sterilization, insecticide, and killing of some aquatic animals that are harmful to the growth of shrimps. Some of the more ferocious fish and the like must be eliminated. Sprinkle the entire pond, soak for a few days, then clean and breed.

3. Stocking

One week before stocking, fertilizer should be applied to improve the water quality. The water depth is about 40 centimeters. It is best to apply cow dung, about 800 pounds per acre of pond. Test the water temperature before stocking, put a few of them in, and then you can stock them all if there is no problem after a day. Shrimp larvae must be soaked and disinfected with bleach for about 10 minutes before stocking. Stocking healthy, uniformly sized shrimp seedlings is conducive to the balanced growth of shrimp. Approximately 8,000 shrimps with a size of 3 cm can be planted in one acre. Don't be too crowded.

4. Feeding

The main food of shrimp is plant feed, wheat bran, soybeans, bean cakes, etc., as well as underwater aquatic plants, algae, and duckweed. Animal feed is egg yolk, insects, aquatic animals. It is common to feed pellets made from artificial formulas, which have relatively comprehensive nutritional content. If you want to grow well, feed more protein-rich foods. Do it once in the morning and once in the evening. The main feeding time is midnight. This time is in line with the feeding time of the shrimp, so you can feed more. The amount of feeding should be enough to eat in an hour.

5. Management

Water quality should be maintained and the water should be replaced regularly. If the color of the water is too dark, there may be problems that need to be improved. Pay attention to the pH adjustment of the water. The water level gradually increases according to the growth of shrimp, and it should be deepened to the deepest level in late summer and early autumn. The water inlet and outlet must be covered and filtered with nets. An aerator is a must, and oxygen is added to the water from time to time. In summer, it is necessary to increase oxygen and change water more frequently.

Rossian shrimp farming has similarities and differences with other shrimp farming. The farming method is mainly determined based on the living characteristics of the shrimp. Pay attention to detail management. The above is the situation of the entire breeding method.
